Description

[Detailed description of the invention] This @ro pertains to a one-tank dehydrating washing machine that rotates a pulsator during washing and rotates a tank during dehydration.
The shape of the fabric softener input case and the balancer case to which it is attached have been improved to facilitate effective washing.

Hereinafter, one embodiment of the suspicious θN will be described based on the drawings. In the figure, 1 is an outer tank for receiving washing water, and 2 is a lid fixed to the outer tank 1. Reference numeral 3 denotes a tank provided inside the outer tank 2, which has a pulsator 4 at the inner bottom and a number of small holes 6 at the side wall. 6 is a balancer case fixed to the upper end of the tank 3, and 7 is a fabric softener injection port 22 at the top.
8 is a partition for the overflow water level formed in the outer tank 1, and 9 is an overflow hose, which is connected to the drain hose 10 at the bottom of the outer tank. It is connected to. 11 is a drain valve that opens and closes the drain hose 1o.

Reference numeral 12 denotes a washing/dehydration switching mechanism section, which is watertightly partitioned from the outer tub 1 by a sealing body 13. 14 is a board for mounting mechanical parts, and 16 is a vibration isolator.

A housing recess 16 is formed in the inner circumferential surface of the balancer case 6 by cutting out a part thereof, and a small protrusion 18 for attaching the charging case is formed in the recess 16 for storing the fabric softener. A lip 17 for engaging the θ hook is provided protrudingly. On both sides of the storage recess 16 on the inner circumferential side of the balancer case, edges 2° for water flow control are provided to protrude inwardly from the reference inner diameter in order from the reference inner diameter.

That is, the inner diameter curvature of the inner peripheral surface of the balancer case 6 is shaped to be R on both sides of the storage recess 16 of the storage case 7.

On the other hand, the fabric softener input case 7 has - a recess 21 correspondingly engaged with the small protrusion 18 and rib 17 of the balancer case 6 in order to be removably attached to the balancer case 6;
A hook 19 is formed. Further, on both sides of the front side of the storage case 7, a water flow control edge 23 having a similar shape is formed so as to be connected to the tip of the water flow control edge 20 of the balancer case 6, and is stored in the balancer case 6. When case 7 is attached, the edge 20°2 for water flow control
3, it is effective as one large water flow control board. The edges 20 and 23 are shaped like eaves so as to be convex toward the center of the balancer case 6. When the eddy current debris is large, or when the water level rises due to flow rinsing, etc., when the washing water flow circulating on the circumference hits the storage case 7, the left and right front surfaces of the storage case 7 Since the part acts as a resistor for the water flow, the water flow overcomes the storage case 7 and flows on the upper surface of the storage case 7 and the balancer case 6.
As a result, washing water flows in, and the fabric softener that has been injected in advance is diluted and neutralized by the washing liquid, making it impossible to achieve its original effect. In addition, if small items such as 7-inch clothes (h'-water line) are floating near the water level during rinsing, they may get caught in the gap between the lancer case 6 and the outer tank 1 or the lid 2, and during spin-drying. Abnormal noise may be generated (・k) This may cause damage to the clothes.Furthermore, if the washing water flow is strong due to changes in the movement of the laundry during rinsing, the washing water flow may be (It may reach not only the lancer case 6 but also the top surface of the lid 2 of the outer tank 1, and although there is a drainage hole in the lid 2, the washing water drips onto the floor and becomes ``important''. There is a possibility that the storage case 7, which was added as an advantage, may actually become a cause of disadvantages.

These measures include washing high water level or oats; -70
- If the water level is significantly lower than the storage case 7, no problem will occur because the water flow will not reach the balancer case 6 or storage case level.

However, in reality, a decrease in water level leads to a decrease in washing capacity, and there is a need to develop an efficient washing machine that secures maximum washing capacity within limited dimensions. In addition, unnecessarily increasing the depth of the washing tub as described above increases the height of the product, which not only makes it easier to put in and take out laundry, but also reduces the amount of raw materials used in the product. This also leads to an increase in costs.

6.～--However, in this embodiment, the curvature of the inner diameter of the clamper case 6 is such that R>τ at the mounting part of the storage case 7, and the water flow finger (control edge 2
0 is formed.

On the other hand, on both sides of the front surface of the storage case, similar edges 23 for water flow control are formed, which are connected to the tip of the edge of the Lancer case 6; Forming -・ru. The water flow that has been circulating on the circumference serves as a surface car resistor that protrudes from the balancer case of the storage case 7, as described above, and the water flow causes the storage case 7 to -
Since there are edges 20 and 23 for controlling the water flow, the force 1 is obstructed and the result is a change in direction inward of the tank 3. .

This results in a high water level for washing.
CI-Even if the water level is brought close to the top of the storage cup,
The various problems mentioned above have been solved, and a dehydrating washing machine with the maximum washing capacity within limited dimensions has been developed, and it has been possible to develop a washing machine that can handle bulk washing, dog washing, etc. This can accommodate the requirement of space saving (rn''/kg) for installation and can be made up of 7 pages.

The fabric softener in the storage case T is sequentially moved within the storage case 7 using repeated dehydration during the washing timer cycle and the centrifugal force during dehydration, and is transferred to the fabric softener 3 during the predetermined rinsing process. It will be automatically entered into.

As mentioned above, this model is able to demonstrate its original value by changing the shape at the time of design without adding additional parts, and at the same time, it can be used in a limited space. It is possible to provide a dehydrating washing machine with maximum washing capacity.
